`CAl-VESTIRULF] DIAPI-IRAGIVI.

'Application led January 17, 1924. Serial No. 686,729.

To all whom t may concern.' i

Be it known that I, HARRY U. MoRroN, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Car-Vestibule Diaphragms; and I hereby declare that the following is a full, clear,

andeXact description of the same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification.

This invention relates to car vestibule diaphragms constructed of flexible material,

such as canvas or the like.

Diaphragms for railway car vestibules are subjected to very severe usage. Usually such diaphragms first fail or become torn or frayed near the lower ends of the legs of the diaphragm. Any portion of the diaphragm may, of course, fail because of bad usage or accident.

It is an object therefore of the present invention to provide a diaphragm either the leg portions or roof portion of which may be readily detached from the other portions when renewal or repair is required.

Another object of the invention is the provision of a sectional diaphragm in which connection between the sections is maintained without the aid of bolts, screws or the like passing through apertures in both sections. i

A further object of the invention is the provision of a diaphragm the roof portion of which is formed by folding single U-shaped strips of fabric.

Other and further important objects of this invention will be apparent from the disclosures in the accompanying drawings and specifications.

The invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described.

On the drawings:

Figure 1 is an end view of a diaphragm constructed in accordance with the present invention.

Figure 2 is a side View of the same.

Figure 3 is a section on the line 3 3 of Figure 1.

Figure 4 is a section on the line 4-4 of Figure 1.

and sewing or riveting such edge to the roof i portion. In this way pockets are formed into which the upper edges of the leg portions may be inserted, and held in place without the aid of bolts, screws or the like fastening means.

The folded edge of the strip 15 spaces the two parts of the pocket apart to allow of the ready entry of the adjacent edge of the leg portion.

The pockets are preferably arranged on the roof portion since the latter does not ordinarily require renewal so frequently as the leg portions. Further, it is desirable that the pockets open downwardly to avoid as far as possible entry of cinders dirt and the like.

I am aware that many changes may be made, and numerous details of construction may be varied through a wide range without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted hereon, otherwise than necessitated by the prior art.

I claim as my invention:

1. A car vestibule diaphragm comprising plurality of detachable sections and pockets on certain sections for the reception of the abutting portions of adjacent sections.

2. A car vestibule diaphragm comprising a roof section and two leg sections and pockets on each end of the roof section adaptedto receive the upper ends' of the leg sections.

3. A car vestibule diaphragm comprising a roof section and two leg sections and pockets on the inner side of each end of the roof section adapted to receive the upper ends of the leg sections.

4. A car vestibule diaphragm comprising a roof section and two leg sections, a stri of fabric secured along its upper edge to the inner side of each end of the roof section to form pockets to receive the upper. ends of the leg sections.

5. A car vestibule diaphragm comprising a roof section and two leg sections, a strip of fabric secured along its upperv edge to the inner side of each end of the roof section with its upper edge turned over to space the body of the strip away from the roof sec.- tion to form pockets to receive the upper ends of the leg sections.

6. A car vestibule diaphragm comprising a roof. section and two leg sections, astrip of fabric secured along its upper edge to the subscribed my name in the presence of two 20 subscribing witnesses.
